Abstract: A stored energy source housing, in particular a high-voltage accumulator housing for a motor vehicle, has a top housing part and a bottom housing part. The bottom housing part has a middle portion and two end portions. The middle portion has a base element on which wall elements are formed laterally and extend along a longitudinal axis. As a result, together with the base element, an arrangement space is formed in regions, and the end portions are arranged at the ends of the middle portion and have wall elements which also form the arrangement space. The end portions are cast parts, and the shape of the middle portion is produced by bending.

Abstract: A rear structure for a motor vehicle includes two longitudinal members, a front cross member and a rear cross member. The front cross member and the rear cross member connect the longitudinal members to one another. The rear structure is a single-piece die-cast component. A motor vehicle includes such a rear structure.

Abstract: A storage housing for an energy store of a motor vehicle includes at least one housing part along which a longitudinal member is arranged on both vehicle outer sides of the storage housing. The longitudinal member is designed as a chamber profile with hollow chambers delimited by chamber walls. In order in this case to provide a storage housing which, on the one hand, has particularly advantageous accident properties, in particular in the event of a side impact on the motor vehicle, and, on the other hand, can nevertheless be produced relatively favorably, the longitudinal members on both vehicle outer sides of the storage housing are formed from in each case at least two partial longitudinal members, the partial cross sections of which complement one another to form an overall cross section.

Abstract: Please replace the original Abstract with the following new Abstract: A housing lower part of an energy storage device housing includes a tub-like element, which has lateral wall elements which extend along a longitudinal axis. Sill elements are arranged on the outer side of the wall elements and each projects beyond the wall elements along the longitudinal axis by way of a longitudinal section. Transverse elements are arranged on the end side of the tub-like element and extend transversely to the longitudinal axis. The sill elements are fastened to the end side of the transverse elements by way of the longitudinal sections.

Abstract: An exhaust air guide of a fuel cell stack is provided, in particular in a motor vehicle, with a cooling device which belongs to the functional environment of the fuel cell stack and is in the form of a cooler structure through which ambient air flows. At least some of the exhaust air of the fuel cell stack is guided into the cooler structure or behind the cooler structure, as viewed in the direction of flow of the ambient air through the cooler structure, to such an extent that, at the cooler structure, the exhaust air flow brings about an increase in the mass flow of the ambient air through the cooler structure in accordance with the jet pump principle or, at the cooler structure, the exhaust air flow, in accordance with the jet pump principle, brings about a pressure difference conveying at least a portion of the ambient air through the cooler structure.

Abstract: An operating method is provided for a fuel cell system with a radiator structure which is flowed through by ambient air and a fuel cell stack, at least part of the outgoing air flow of the fuel cell stack can be guided onto the radiator structure such that, at the radiator structure, the guided outgoing air flow causes an increase in mass flow of the ambient air through the radiator structure according to the jet pump principle. At least part of the outgoing air flow of the fuel cell stack can be guided through a gas expansion machine. The division of energy which is contained in the outgoing air flow and can be recovered in the gas expansion machine and/or at the radiator structure according to the jet pump principle is changed by an electronic control unit in a manner which is adapted to boundary conditions.
